So trying creating a family with the simsun font :
> display : "& # 30003;" with a first little square (character not found, I guess).

I cannot write in my ASP code :
Set cCell = cRow.AddCell2( "?", , , , , 2 )
Because my source files encoding does not allow it. So I have to write "something" that can be understood as a special character, just like the browser display "?" when I write "response.Write("& # 30003;")"
